摘　　要：近年来,光学器件和数字化处理技术的高速发展为全光纤相干连续波激光雷达探测系统的小型化提供了基础。该雷达具有测速精度高、距离分辨率高、体积小、重量轻、易于装载等特点。本文首先介绍全光纤相干连续波激光雷达的测距测速原理,其次针对全光纤相干连续波激光雷达的性能指标设计了一套波形参数,并对该模型进行仿真实验,最后进行外场实际测量。仿真数据和实验数据均表明,利用该参数可以达到高的距离分辨力（1 m）,大的速度可测范围（-100~100 m/s）,高的速度准确率（0.5%）,完成了设计指标。In recent years, the high-speed development of optical devices and digital processing technology has provided the basis for the miniaturization of the coherent continuous wave laser radar detection system. The radar has the advantages of high accuracy, high resolution of distance, small size, light weight and easy loading. In this paper, the principle of all fiber coherent continuous wave laser radar ranging and speed measurement is introduced firstly. Secondly, a set of parameters are designed according to performance indicators of all fiber coherent continuous wave laser radar. Then several simulations are done. At last, actual measurements using the radar are made. The simulation data and experimental data show that the high range resolution（ 1 m） ,the large velocity range（ - 100 - 100m/s） and the high accuracy rate（0. 5% ） can be achieved by using this parameter. The design target has been achieved.
